With the continuing trend toward lighter viscosity motor oils, AMSOIL has expanded the Signature Series, XL and OE lines. The Signature Series line now includes a 5W-20 oil (ALM), while the XL and OE lines now each include a 0W-20 oil (XLZ, OEZ). Like the other oils in their respective lines, each new oil is formulated to provide outstanding protection and performance and meet the latest API SN/ILSAC GF-5 specifications. XL and OE 0W-20 are API licensed.
